Title: Compact file for letters and other documents
Inventor: MITSUYAMA MASUHIRO
IPC: B42F7/02
Filed: 1991-10-31
Abstract: ABSTRACT OF THE DISCLOSURE         Disclosed is a file for holding various kinds of documents or letters, which is constructed essentially of a rigid rectangular plate, a cover sheet and soft pliable portions provided along at least the longitudinal side edges of the main plate.  The cover sheet is dimensioned so as to cover the main plate and the soft pliable portions and is fused to the pliable portions and bottom end of the main plate.  The top end of the cover sheet is left separable from the main plate so that papers or letters can be inserted or removed.  The structure of the file is such that when the file is empty, the cover sheet is closely adjacent the main plate since no separation member is disposed between the main plate and the cover sheet.  This makes the file very flat and convenient to transport.  Nevertheless, when it is desired to open the file, the cover sheet can merely be pulled forwardly, whereby the pliable portions bend forwardly and papers or letters can be inserted into or removed from the pocket formed between the main plate and the cover sheet.

Title: Method for crystallizing alpha-l-aspartyl-l-phenylalanine methyl ester
Inventor: MURAKAMI TSUGIO
IPC: C07K5/075
Filed: 1992-07-20
Abstract: A method for crystallizing .alpha. -L-aspartyl-L-phenylalanine methyl ester (APM) by cooling. In this method, crystals of APM are subjected to crushing, and the crushed APM crystals are used as seed crystals for growing APM crystals. By the use of crushed seed crystals, the generation of fine secondary APM crystals can be suppressed, and the width to length ratio of resulting APM crystals becomes larger. As a whole, big APM crystals having improved filtering and drying properties can be obtained. Such crystals can be advantageous with regard to production, quality and handling.  The precipitation of APM crystals proceeds quite efficiently with only a small quantity of crushed seed crystals. This invention also relates to crystallization of APM using in situ prepared crushed seed crystals.
